We have to calculate the volume of these objects.
Density=mass/ volume ⇒volume=mass/ Density.
1)Object a
Data:
mass=500 g
density=5 g/cm³
Volume=500 g/ (5g/cm³)=100 cm³
2)volume of object b
Data:
mass=650 g
density=6.5 g/cm³
Volume=650 g /(6.5 g/cm³)=100 cm³
Therefore, the volume of these objects is the same.
Answer: both objects would displace the same amount of liquid, because the volume would be the same.
